I found this expression on the news channel about the crypto currency: "Anyone who will try to buy coffee for cash in 2023, runs the risk of causing laughter from the seller, that he does not use crypto currency."
how do you think, is it realistic? Can a crypto currency replace national money?
I think that it's possible, but it will take more time.
I'm sure that the crypto currency will replace real money, the question is only in time. The only thing that I do not quite agree is that the national money will disappear completely, as it seems to me, they just turn into a crypto currency))
